Catalytic Reverse Shift Reaction-A Kinetic Study

Reaction Rate of Water-Gas Shift Reaction

“…As seen from Tables I and II, the constancy of k, and k2 is fairly good, which reveals the fact that the rate equations (6) as well as (10) are sufficiently accurate at least for the practical purpose.…”

“…But in this case Eq. (6) (6) reproduces the results of the water-gas shift reaction, the reaction rate of the reverse shift reaction must be given as: (10) As in the case of the forward reaction, also, the relation of Z' and t is derived for the reverse shift reaction from Eq. (10), as (11) (12) Calculated values of kz for all the experimental conditions are tabulated in Table II.…”

Modeling the Water-Gas Shift Reaction

“…Numerous kinetic studies (Barkley, et al, 1952; Bohlbro, 1961Bohlbro, , 1962Bohlbro, , 1963Bohlbro, , 1964Bohlbro, , 1966; Giona et al, 1961;Hulburt and Vasan, 1961; Kodama, et al, 1953; Kul'kova and Temkin, 1949; Paratella, 1965;Shchibrya, et al, 1965) on the water-gas shift reaction have been conducted using iron oxide catalysts, and there is general agreement among most of the results reported which can be summarized as follows: the rate of reaction is approximately proportional to the carbon monoxide concentration; the rate is usually retarded by increasing carbon dioxide concentration and almost independent of hydrogen concentration and independent of steam concentration when it is in excess of the stoichiometric amount.…”

Simulation of High-Temperature Water-Gas Shift Reactors

“…Dev., Vol. 16,No. chenko, 1959,1962; Barkley et al, 1952;Bohlbro, 1964; Bortolini, 1958; Goodridge and Quazi, 1967;Hulburt and Srinivasan, 1961;Kirrillov, 1959; Kodama et al, 1952Kodama et al, ,1955; Kulkova and Temkin, 1949;Popov, 1957;Puri et al, 1973) propose different rate equations. Each of the latter rate equations is of complex order and different from those proposed by others.…”
